so you seem like the kind of guy who could help me with something. i am a total beginner so bear with me. so i have a led that i have a power supply going to but its not lighting up. the thing is i don't know if i need more voltage or more current to light it up. i should have been paying attention in physics. so i need a step up or step down trransformer right? and what kind do i need? if anyone else knows they can help me out as well. sorry if this seems stupid. you are awesome by the way.

@freakface666666

Your power suplly has to have a voltage of around 2 volts. More voltage will destroy the LED. Also pay attention to the polarity of the LED and the power supply (you need a DC supply of course!)

[freakface666666]

@DrCassette so if i were to hook up an extra battaery i suppose it would be easier than dealing with transformers. i cant figure out the polarity of the led though. and if i have enough voltage i can hook up 2 leds in parralelle right?

Nice.Whats the Name of the Song at start??

[DrCassette]

@LtdBoomer

I don't know.

[padly88]

do u have schematic of portable amp.?

[FelixTheHouseFreak]

Very nice,

I built my first electronic device when i was about 6 or 7 and it was a crystal radio. Since then i kept going and it is great fun.

[therage001]

cool stuff man

[DrCassette]

Thank you!

[thepolk1]

man alot of universites where you live in germany must want you because you are smaart man you know more than most older people

I've seen those Ethernet cable testers commercially available, the ones I've seen have 2 units, and you run the cable between them, one unit is the master unit which contains the battery, both units have the test LED's on them. I remember an admin technician at a school I used to attend had one for checking network cables. They're a very handy device to have around if you do a lot of network troubleshooting.

Tin-can amps,crystal radios,amps made from boomboxes,selector boxes,what next?!Excellent work!

[DrCassette]

Thank you!

Next I plan to built a quadrophonic amplifier TOTALLY by myself (without using anything made by somebody different) I'll make a video about that of course.

[AG3304]

Best of luck with the quadrophonic amp,look foward to the video.

[DrCassette]

Thank you!

[AG3304]

No problem.

[umajunkcollector]

The tin can amp would be very hard on 9v batteries if it was three watts per channel. But it was kewl!

[coolbluelights]

I like that little amp you built into that tin^^ very neat :D I would need that to use the crystal radios because of my hearing problems :/ that second Xtal set is really interesting!

[AllAmericanFiveRadio]

Great projects. Good way to learn, fun too. I made a few crystal radio sets, some kits, some totally home brew. One I took to grade school, I had built the crystal radio into a cigarette lighter. One favorite think I like to do was to jam my older brothers radio using my crystal set, until threatened with bodily harm.
